“The singular multiplicity of this universe draws my deepest attention. It is a thing of ultimate beauty. Leto II”

“Since every individual is accountable ultimately to the self, the formation of that self demands our utmost care and attention.”

“In the wrong hands,” Leto said, “monolithic centralized power is a dangerous and volatile instrument.” - “And your hands are the right ones?”

“But attack can take strange forms. And you will remember the tooth. The tooth. Duke Leto Atreides. You will remember the tooth." -Dr.Yueh”

“Every judgment teeters on the brink of error,” Leto explained. “To claim absolute knowledge is to become monstrous. Knowledge is an unending adventure at the edge of uncertainty.”

“There is in all things a pattern that is part of our universe. It has symmetry, elegance, and grace - these qualities you find always in that the true artist captures. You can find it in the turning of the seasons, the way sand trails along a ridge, in the branch clusters of the creosote bush of the pattern of its leaves. We try to copy these patterns in our lives and in our society, seeking the rhythms, the dances, the forms that comfort. Yet, it is possible to see peril in the finding of ultimate perfection. It is clear that the ultimate pattern contains its own fixity. In such perfection, all things move towards death.”

“Come, come," the Baron said. "We don't have much time and pain is quick. Please don't bring it to this, my dear Duke." The Baron looked up at Piter who stood at Leto's shoulder. "Piter doesn't have all his tools here, but I'm sure he could improvise.""Improvisation is sometimes the best, Baron.”
